Yuav ua li cas xaiv txoj hauv kev tsim nyog ntawm granulation thaum cov ntaub ntawv sib txawv raug hloov kho?

Thaum cov resins ntshiab raug "hloov kho", feem ntau muaj kev hloov pauv hauv txoj kev granulation uas tsim nyog dua.

Piv txwv li:

• Kev sau, tshwj xeeb tshaj yog kev sau ntau, feem ntau ua rau LLDPE lossis LDPE yas granulation tuaj yeem hloov pauv los ntawm dej nplhaib granulation mus rau cua txias pwm nto kub. Ob qho tib si ua rau muaj zog, thiab txuag hluav taws xob (txuag tom qab ziab); cov noob zoo nkauj thiab txo qhov poob ntawm cov hmoov ntug.

• Zoo dua, vim muaj cov iav fiber lossis carbon fiber, yog li qee cov khoom siv cua txias (polyethylene siab, ABS, thiab lwm yam) rov qab mus rau cov kab txiav txias ib txwm muaj (dej). "General" thiab "engineering" (plastics) tsis muaj qhov tshwj xeeb.

• Ruaj khov, zoo li cov khoom siv TPV bumper feem ntau siv (PP + EPDM + POE dynamic vulcanization), vim yog qhov sib xyaw ntawm cov hmoov roj hmab hauv PP theem txuas ntxiv mus, ua rau lub nplhaib dej kub dhau los ua qhov nyiam. Nws zoo nkauj thiab muaj nqis zoo.

○ Kev rho tawm rov qab

(1) Cov khoom siv cable txuas nrog tshuaj lom neeg (XL-PE) yog qhov kev xaiv zoo tshaj plaws ntawm qhov chaw tuag txias cua. Hauv ntau lub Hoobkas khoom siv cable,ntxaib ntsia hlau/ib lub ntsia hlau ob kauj ruam tshuab + cua txias kub (lossis eccentric kub) yog SPVC thiab XLPE sib xws nrog kev tsim khoom txheem.

(2) Hauv kev tsim khoom thiab kev tsim cov polypropylene muaj zog yaj (HMS-PP), PP cov tshuaj tiv thaiv extrusion branched tuaj yeem txais cov khoom kub kub zoo dua.

Cov ntaub ntawv hloov kho ntau dua lossis cov qauv txiav ua pawg ntau dua

• Cov khoom siv rwb thaiv tsev SPVC cable los yog cov khoom siv kho mob pob tshab, zoo dua yog tias txhua yam cua txias pwm nto kub. RPVC kuj zoo ib yam, tab sis me me xwb.

• Polystyrene, tsis hais HIPS lossis GPPS, xaiv txoj siv casting (inclined water cooling) txiav kab yog feem ntau.

• Cov khoom siv ABS feem ntau siv, feem ntau xaiv rub (dej) txiav txias (cov duab nyias thiab ntev yog qhov nrov tshaj plaws). Tib neeg tau sim cua txias fervor lossis dej nplhaib fervor txhua yam tsis muaj teeb meem, cov duab ntawm cov noob kuj zoo nkauj (spherical zoo). Thaum lub peev xwm tsim khoom ntau dua 3-4t / h, nws yog qhov tsim nyog hloov mus rau hauv qab dej kub casting lossis siv txoj siv sia casting tshuab.

• Cov khoom siv cable uas muaj shielded lossis semi-shielded, xaiv me me ntawm lub nplhaib dej, xaiv ntau ntawm cov dej hauv qab (xav ua).

• Silane cross linked cable khoom, kab me me xaiv dej nplhaib, loj (xws li 96/250 kab) xaiv hauv qab dej (kub).

• HFFR (cov khoom siv cable uas tsis muaj pa luam yeeb halogen tsawg) tsim thiab granulation, sib xws nrog XLPE cov khoom siv, tab sis qhov kev teeb tsa ntsia hlau extruder hloov pauv.

• Copolymer formaldehyde (POM) kawg, tuaj yeem xaiv lub nplhaib dej lossis hauv qab dej (txiav).

• TPU (thermoplastic polyurethane elastomer), ntau yam kub hauv qab dej, tab sis tib qho kev taw qhia ntawm qhov seem extrusion metering yuav tsum tau kho rau kev tsim kho siab.

PET filament master batch, tuaj yeem txiav txias nrog rub (dej) lossis pov nrog txiav txias.

• Kev txo qis kev tso pa tawm nrov PPC (polypropyl carbonate), tuaj yeem sib xyaw nrog yuav luag txhua hom kev puas tsuaj resin (TPS, PLA, PBAT, PBS, PHBV, PHA, PVA, PCL, PGA) thiab granulation.

• Cov khoom siv ua los ntawm cov iav fiber ntev (LFI-PP, LFI-PA) uas tau muab nchuav rau hauv.
• Cov ntaub ntawv siv feem ntau ntawm PE zaj duab xis ua pa tau los ntawm lub Hoobkas - sib tov thiab ua kom cov khoom sib xyaw ua ke;

• Cellulose acetate sib xyaw ester molding plastics - sib tov granulation;

• TPEE (block copolymer ester roj hmab) - kev sib xyaw ua ke;

• K resin - granulation ntawm cov khoom tsim tawm thiab cov ntaub ntawv hloov kho;

• SBS, SIS, SEBS thaiv elastomer granulation lossis devolatilization granulation;

• POE graft, graft EPDM thiab lwm yam khoom siv toughening uas sib xws - sib tov granulation;

• Cov ntaub ntawv siv rau kev khawb cov polyethylene uas muaj molecular weight siab heev (UHMW-PE), xws li kev sib xyaw granulation;

• Polyethylene wax (PEW) — batching, granulation thiab micro-granulation;

• Petroleum resin (C5 lossis C9) — cov khoom xyaw thiab cov granulation tshwj xeeb;

• Nylon (PA6+PA12+SiC) abrasive hlau sib tov extrusion thiab txiav.
